Cool Mist humidifiers?

Well in the spring time where I am at our humidity isn't too bad,infact right now it is like it was in the winter...LOW.Temps outside are rising but for the last two days it has been perfect 65-70 degrees outside with about 30% RH.

This winter I ran into a problem in my grow,the humidity outside was so low and therefore lights on in my cab the RH% was low (25-35%).My budd who I used to grow shrooms with was telling me about cool mist humidifiers and how he used one for his latest psilocybe cubensis grow.He plugged it in (not set up to his grow) and withing a minute there was a cool mist.I couldn't tell just how cool it was becuase my handswere already cold but it definitly made them feel cooler.

Anyways,I was wondering if I could use one of these in my cab or rig one up to my cab to raise the humidity when the light is on.

I know it is a cool "mist" humidifier and that scares me,is there any danger of using one of these in a grow (water particles building up?) and will I have to set my fan on a timer,becuase I cant do that until I get my 6" 440cfm inline,all I have is 4" 170cfm inline and that will barely cut it without central A/C being dipped to 65F this time of year.

It would work great. I have one in my room but not the cab because i need it for my own comfort too. Doesn't leave any water droplets anywhere... that'd be more a problem from a warm mist type humidifier, especially if you didn't have good airflow.

Raised the humidity in here from 30 to 55, but that is in a large room with it running constantly. A new one will have a built in meter to tell it when it needs to come on... you set the humidity you want, and it does the rest. If it's not running all the time, I wouldn't need to refil mine for a couple days. As it is, I have to fill it up every night.

How large of a room does yours sit in akrazy?

The room my cab sits in is about 10' x 15 take a little from the width give or take from the length.


I have another wuestion.You say you have your sitting in the room,not in the cab.You also said that it raised the rooms RH% from 30% to 55%.Did you notice a difference in the grow cab's RH% after installing the cool mist in your room?

My a/c hood doesn't have the glass sheild in it becuase my exhuast is setup to both cool the light and ventilate the cab so I am worried about any electrical problems.I plan on maybe getting the glass becuase ithink without it the air has too much time to circulate around the bulb before getting sucked out and I use a 4" 170cfm inline for those purposes but want to step up to a 6" 440cfm inline for summer.

My room's about the same size. It rased the RH in the cab from 25 to 35-40. The closer to the light, the least humidity.

Thats dfinately a given the closer to the light source the less humidity.I really just need to step up to a 6" inline.

Well if you say there is no risk of electrical problems caused by the mist then I will go out and buy one in a few days.My neibor was having a huge sale the other day and I noticed she had a cool mist humidifier and no one picked it up,I'll see if she still has it.

Do the newer ones come with a setting knob to set desired humidity levels?

Yeah, they have it all built in, like an ac. Just get a small one, and don't put the humidity too high, if you're worried about electrical problems. It would have to be really humid before it'd cause any standing water, and it would shut it'self off before then. There is no visible "mist" that comes out, just humid air.
